title = "Detecting Usage of Deprecated Web APIs via Tracing (Summary)",
abstract = "While deprecation for local APIs is well-researched and supported by tools, web and other remote APIs have scarcely been studied. The few previous approaches focused on static analysis, accepting essential limitations. We introduce a dynamic approach that first detects calls to web APIs using tracing and, subsequently, checks the called APIs for deprecation using an API specification, response meta-data, or a knowledge base.",

abstract = "The special interest group software reengineering (FG-SRE) of the German Informatics Society (GI e.V.) meets to discuss and move forward the state-of-practice and research of software reengineering in the German-speaking countries since 1999. In 2021 we started an initiative to collect and share the knowledge about the state-of-the-art in software reengineering to help practitioners and researchers to get an understanding of the field. In the last WSRE workshop, the team presented the initiative's goals and plans. In this contribution and the associated talk, we report on our recent progress and expected results of this initiative.",

title = "API Deprecation: A Systematic Mapping Study",
abstract = "Application Programming Interfaces (APIs) are the prevalent interaction method for software modules, components, and systems. As systems and APIs evolve, an API element may be marked as deprecated, indicating that its use is disapproved or that the feature will be removed in an upcoming version. Consequently, deprecation is a means of communication between developers and, ideally, complemented by further documentation, including suggestions for the developers of the API's clients.API deprecation is a relatively young research area that recently gained traction among researchers. To identify the current state of research as well as to identify open research areas, a meta-study that assesses scientific studies is necessary. Therefore, this paper presents a systematic mapping study on API deprecation to classify the state of the art and identify gaps in the research field. We identified and mapped 36 primary studies into a classification scheme comprising general and API-specific categories.Furthermore, we identified five major gaps in previous research on API deprecation.",

title = "Decision-Making About Federated Digital Twins – How to Distribute Information Storage and Computing",
abstract = "Digital Twins are commonly used as virtual representations of physical objects in manufacturing industries. Information for Digital Twins may be collected from multiple sources and stored in a distributed manner, leading to a Federated Digital Twin. Since decisions about such a federation are crucial for the system and its architecture, they should be guided by reliable and well-evaluated methods. However, current research is focused on distributed data sources but is missing decisions about the distribution of the digital twin itself. We present an approach to partition Federated Digital Twins by classifying information types, computing resources, and concerns of data suppliers. Furthermore, we show how decisions are made based on the Decision Model and Notation standard and evaluate the approach using an industrial case study.",
